These custom modifications were done to add several very cool features to the ET-4. Included is an effects loop which doubles as an external audio input with clipping indicator. Headphone jack with volume control, and a knob for filter resonance. Separate outputs were also added for a customer that wanted to send the sound of each oscillator to different amplifiers on opposite sides of the stage – very cool!
We just finished this ET-4 for a customer that requested a few extra features. Expression pedal/CV inputs to control the pitch of each oscillator, pulse width modulation and VCA gain. We also added knobs to manually hold the position of either intensity key.
After lots of hours of wood dust, we’re now working through our 19-step finishing procedure. The results are definitely worth the effort though, here are a few pictures.
After getting several requests for a left-handed version of the ET-4, I’m happy to say that we recently completed two custom lefty ET-4’s. Instead of just moving the intensity keys to the other side, we mirrored everything about the instrument to keep it equally ergonomic. If you want a lefty ET-4, please let us know.
